Audio Input Microphone [1..8] EchoControl Mode
The echo canceller continuously adjusts itself to the audio characteristics of the room and
compensate for any changes it detects in the audio environment. If the changes in the audio
conditions are very significant the echo canceller may take a second or two to re-adjust.
Requires user role: ADMIN
Value space: <Off/On>
Off: Echo Control should be switched Off if external echo cancellation or playback
equipment is used.

Once selected, echo cancellation is active at all times.
Example:
Audio Input Microphone 1 EchoControl Mode: On
